Pair check
Can B stand in for A?
Your supplier or distributor offered one part in place of another. Enter both, and XrefBase states exactly the claim it holds about that pair — and nothing stronger.
How to read a verdict
The verdict says which of these B is to A, and quotes the source behind it.
- Published replacementsAsserts substitutionThe only results asserting a replacement relationship. Confirm application-specific fit before use.
- Functional equivalentsNot a substituteSimilar function, not a confirmed drop-in. Engineering review is required before substitution.
- Superseded predecessorsNot a substituteProduct history, shown for context only — not an alternative to this part.
- Same seriesNot a substituteSame family, different configuration. Family navigation, not a substitution claim.
- VariantsNot a substituteThe same part in a different keying, colour or packaging suffix.
- Mating counterpartsNot a substituteWhat this component plugs into. These are never substitutes for it.
- No relationship recordedNot assessedNothing links the two parts yet. That is not a finding that B was checked and rejected.
